NON-REFILLABLE BOTTLE.

SPECIFICATION fcrming part of Letters Patent No. 714,974. dated December 2, 1902.

Application filed August 24.1901. Serial No. 73,134. (No model.)

To all whom it may concern- Be it known that I, WILLIAM F. TnoMrsoN,` a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented Improvements in Non-Refillable Bottles, of which the following is a' specification.

This in vention relates to non-reiillable bottles, and has for its object to provide a simple construction that may be made at comparatively low cost and that maybe efficient to prevent refilling of the bottle after being once emptied of its contents.

The invention consists of the construction hereinafter set forth.

In the accompanying drawings, forming' part of this specification, and in which like numerals of reference designate corresponding parts, Figure 1 is a vertical Sectional elevation of the upright neck of a bottle embodying` the invention. Fig. 2 is a similar View showing the bottle tilted and the Valve open. Fig: 3 is a side elevation of the Valvecase forming part of the invention. Fig. 4 is a plan view of the Valve-case. Figs. 5 and (5 are sectional views of the Valve-case on the lines 5 5 and 0 6,1'espectively, of Fig. 4; and Fig. 7 is a sectional view on the line 7 7of Fin. 4.

Referring now more particularly to the specific embodiment of the invention, the neck 1 of the bottle is provided with a Valve-seat 2, upon which the Valve 3 is designed to rest to close the neck. l/Vithin and partially filling the neck is a Valve-case 4, open at the bottom and having a closed top 5. Between the neck of the bottle and the Valve-case are a number of obstructions, preferably integral with the Valve-case. These obstructions serve the purpose of preventing access of an implement to the Valve 3 in case any attempt is made to surreptitiously interfere with the operation of the Valve. They also serve to hold the Valve-case in position by contacting with the inner wall of the neck. Of these projections the projections 6, 7, and 8 are arranged near the top of the Valve-case. A little farther down the projections 9, 10, and 11 are arranged, and still farther down are arranged the projections 12, 13, and 14. At the bottom are arranged the projections 15, 16, and 17. These projections are in the form ofshort circumferential fianges having intervening spaces for the outflow of liquid. The flanges, which are arranged between the upper and lower ends of the Valve-case, are provided with short ribs, such as 18, on the projectiou 11. The Valve-case also has at the bottom openingrs 19, 20, and 21, through which the escaping` liquid fiows. The Valve-case rests immediately above the Valve-seat 2. 23, 24, and 25 are air-ven't openings to prevent theiformation of an air-cushion above the Valve and the consequent interfcrence with its proper operation. In its best form the valve is in the form of a tube, open at the top and closed at the bottom, closely fitting and working within the Valve-case, as shown. It is generally-provided at its zbottom with vprojections 26, 27, and 28, which work in the openings 19, 20, and 21 and serve to center the Valve within the Valve-case. I preferably provide a spring 29, tending to assist the Valve to its seat. In its best form this spring is formed of coiled Wire and is arranged within the Valve-case and Valve, as shown, and is normally under slight compression.

The bottle is preferably provided with a separate cap 30, which may be corked in the usual manner. This cap is provided with a shoulder 31, which rests upon the projections 6, 7, and 8 of the valVe-case When the cap is sealed in place. For the purpose of sealing the cap'it is provided with two projections 32 and 33 on its inner wall, which engage in corresponding recesses 34: and 35 on the Outer wall of the neck, thus forming a bayonetjoint. The neck and cap are also provided with corresponding` recesses for the reception of a sealing-spring 36. When the cap is'fitted on the neck and pushed part way home, the spring 36 is inserted in its place, and the cap is then pushed fully home and turned so as to lock the bayon et-joint, whereupon it will be securely sealed.

In the operation of the bottle the Valve rests by gravity upon its seat when the bottle is npright. l/Vhen the bottle is inverted'or the neck turned down, as shown in Fig. 2, the valve moves by gravity along the Valve-case, Which has an unobstrncted space above the Valve and permite the latter to move freely The liquid thereupon floWs through therein;

IOO

the openings 19, 20, and 21, around the Valvecase, and out through the mouth of the bottle. When the bottle is in a horizontal position, the spring 23 operates to move the Valve to its seat. When the bottle is between a horizontal and an upright position, the Valve also moves to its seat. When the bottle is entirely emptied of its contents, it is filled by breaking off the cap 30 and removing the Valve-case and Valve, Which may be readily done. When the bottle is refilled at the bottling-works, a new cap 30 is attached.

While I have shown the invention in the best form now known to me, I do not Wish to be restricted to this precise form, as the device may be varionsly embodied Without departing from the scope of the invention. For

' example, the Valve-seat need not necessarily be formed integrally With the neck of the bottle, but may be provided in any other suitable way. v

What I claim, and desire to secure by Letters Patent, is-

1. In a non-refillable bottle, the combination with the neck; of a Valve-seat; a Valvecase arranged Within and partially filling the neck above the Valve-seat, said Valve-case being closed Vat the top and having openings in its Wall near the bottom and being provided With obstructions on its outer Wall to prevent access of an implement to the Valve; and a Valve arranged to move to and fro in said Valve-case so as to cover and uncover said openings in the Valve-case and rest upon the Valve-seat, the Valve-case having an unobstructed space for the free movement of the Valve therein by gravity.

2. In a non-refillable bottle, the combination With the neck; of a Valve-seat; a Valvecase arranged within and partially filling the neck above the Valve-seat, said Valve-case being closed at the top, and having openings in its wall near the bottom and being provided with obstructions on its outer Wall to prevent access of an implement to the Valve; a Valve arranged to move to and fro in said Valvecase so as to cover and uncover said openings in the Valve-case and rest upon the Valveseat, the Valve-case having an nnobstructed space for the free movement of the Valve therein by gravity; and a spring tending to assist the Valve to its seat.

3. In a non-refillable bottle, the combination With the neck; of a Valve-seat; a Valvecase arranged Within and partially filling the neck above the Valve-seat, said Valve-case being closed at the top, and having openings in its Wall near the bottom and being` provided With obstructions on its Outer Wall to prevent access of an implement to the Valve; ahollow tubular Valve arranged to move to and fro in said Valve-case so to cover and uncover said openings in the Valve-case and rest upon the Valve-seat, the Valve-case having an unobstrncted space for the free movement of the Valve therein by gravity; and a coiled spring arranged Within the Valve-case and Valve to assist the Valve to its seat.

4. In a non-refillable bottle, the combination with the neck; of a Valve-seat; a Valvecase arranged within and partially filling the neck above the Valve-seat, said Valve-case being closed at the top, and having openings in its wall near the bottom and being provided With obstructions on its Outer Wall to prevent access of an implement to the Valve; ahollow tubular Valve arranged to move to and froin said Valve-case so as to cover and uncover said openings in the Valve-case and rest upon the Valve-seat, the Valve-case having an nnobstructed space for the free movement of the Valve therein by gravi ty, the Valve having 'exterior projections fitting in the said openings in the wall of the Valve-case; and a coiled spring arranged within the Valve-case and Valve to assist the Valve to its seat.

In testimony whereof I 'have signed my name to this specification in the presence of two suhscribing Witnesses.
